    Abstract The Gram-staining negative, oxidase and catalase negative strain KC-ST17ᵀ, isolated from saline-alkali land, was characterized using a polyphasic approach to determine its taxonomic position. Using 16S rRNA gene sequence analysis, the highest similarity of strain KC-ST17ᵀ was found with Nitratireductor pacificus CCTCC AB 209302ᵀ (97.2%). Cells are aerobic, non-motile, and rod-shaped. The isolate was found to be able to grow in NaCl concentrations of 0–4.0%. The assembled genome of strain KC-ST17ᵀ had a total length of 4.9 Mb with a G + C content of 62.7%. According to genome analysis, strain KC-ST17ᵀ encodes genes involved in the reduction of nitrate to nitrite, which may play a role in the utilization of nitrogenous compounds from the soil as an immediate source of energy. Based on the phenotypic characteristics and phylogenetic analysis, strain KC-ST17ᵀ was confirmed to represent a novel species in the Nitratireductor genus; thus, the name Nitratireductor luteus sp. nov. was proposed. The type strain of this species was KC-ST17ᵀ (= KCTC 92119ᵀ = MCCC 1K07309ᵀ).

    Abstract: A novel bacterial strain, TLK-CK17ᵀ, was isolated from cow dung compost sample. The strain was Gram-staining negative, non-gliding rods, aerobic, and displayed growth at 15–40 °C (optimally, 35 °C), with 0–5.0% (w/v) NaCl (optimally, 0.5) and at pH 6.5–8. ...

    Abstract A novel bacterial strain, TLK-CK17ᵀ, was isolated from cow dung compost sample. The strain was Gram-staining negative, non-gliding rods, aerobic, and displayed growth at 15–40 °C (optimally, 35 °C), with 0–5.0% (w/v) NaCl (optimally, 0.5) and at pH 6.5–8.5 (optimally, 7.0–7.5). The assembled genome of strain TLK-CK17ᵀ has a total length of 4.3 Mb with a G + C content of 68.2%. According to the genome analysis, strain TLK-CK17ᵀ encodes quite a few glycoside hydrolases that may play a role in the degradation of accumulated plant biomass in compost. On the basis 16S rRNA gene sequence analysis, strain TLK-CK17ᵀ showed the highest sequence similarity (98.9%) with L. penaei GDMCC 1.1817 ᵀ, followed by L. maris KCTC 42381 ᵀ (98.3%). Cells contained iso-C₁₆:₀, iso-C₁₅:₀, and summed feature 9 (comprising C₁₇:₁ ω9c and/or 10-methyl C₁₆:₀), as its major cellular fatty acids (> 10.0%) and ubiquinone-8 as the exclusively respiratory quinone. Diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol prevailed among phospholipids. Based on the phenotypic, genomic and phylogenetic data, strain TLK-CK17ᵀ represents a novel species of the genus Lysobacter, for which the name Lysobacter chinensis sp. nov. is proposed, and the type strain is TLK-CK17ᵀ (= CCTCC AB2021257ᵀ = KCTC 92122 ᵀ).

    Abstract A third dose of inactivated virus vaccine (IVV) boosts neutralizing antibodies, reducing SARS-CoV-2 transmission rate and COVID-19 severity. However, the impact of RBD-elicited antibodies and their neutralizing activity by the boost of IVV is unknown. We investigated the impact of IVV's boost shot on RBD-elicited antibodies and their neutralizing activity in 18 subjects receiving the second and third IVV doses. Using an RBD antibodies depletion assay, we assessed the neutralizing activity of RBD-elicited antibodies. After the second dose, RBD-antigen elicitation accounted for ∼60% of neutralizing activity, which increased to 82% after the IVV boost against ancestral SARS-CoV-2. Depleting class 3 and class 4-specific antibodies with the Beta-RBD protein revealed that NAbs targeting RBD class 1 and class 2 subdomains increased from 57% to 75% post-boost. These findings highlight the significant enhancement of RBD-specific antibodies, especially against RBD class 1 and class 2, with IVV booster doses. Our study offers valuable insights for optimizing COVID-19 vaccine strategies.

    Abstract Small supernumerary marker chromosomes (sSMCs) are a group of rare chromosomal anomalies, which pose challenges in the clinical practice of prenatal diagnosis and genetic counseling. This study enrolled an extended family with an underage male patient displaying infantile seizures, intellectual disability, and retarded speech and psychomotor function. A series of multiplatform genetic detections was conducted to explore the diagnostic variation. Whole exome sequencing (WES) and chromosomal microarray analysis (CMA) indicated a mosaic sSMC derived from the pericentromeric region of chromosome 8 in the patient, which was confirmed using cytogenetic methods. The proband and his mother, who carried this mosaic variant, exhibited strong phenotypic variability. We also ruled out the pathogenicity of a

    Abstract Butafulvene is a constitutional isomer of benzene, comprising a cyclobutene skeleton bearing two exocyclic conjugated methylene units. As a result of the intrinsic high strain energy and anti-aromaticity, the preparation of butafulvene compounds has been a fundamental issue for the development of butafulvene chemistry. Here an efficient palladium-catalysed coupling protocol involving propargylic compounds has been developed, providing a solid and versatile strategy for the rapid assembly of symmetric butafulvene derivatives. Based on mechanistic studies, two complementary mechanisms, both involving palladium catalysis, have been confirmed. With the mechanism unveiled, the synthesis of non-symmetric butafulvenes has also been achieved. Advantages of this strategy include tolerance to a wide range of propargylic molecules, mild reaction conditions, simple catalytic systems and easy scalability. The synthetic potential of the products as platform molecules for cyclobutene derivatives has also been demonstrated.

    Abstract Recently, China has attached great importance to promoting immunization, prompting the media, scholars, and public to focus on its coverage and efficacy. This study aimed to understand the factors influencing parental willingness to have their school-aged children vaccinated with quadrivalent influenza vaccines (QIVs). A cross-sectional study through face-to-face interviews was conducted between September and December 2018. Forty-four kindergartens and primary and junior high schools were randomly selected via stratified three-stage cluster sampling. Of 4,430 participants, 24.6% reported having heard of QIV and 24.2% reported having previously received information on QIV. Of these, 42.8% expressed willingness to obtain the QIV for their children. A junior college degree (adjusted odds ratio [aOR] = 1.447; 95% confidence interval [95% CI]: 1.202-1.742), higher influenza knowledge level (medium level, aOR = 1.150, 95% CI, 1.006-1.314; high level, aOR = 1.332, 95% CI, 1.045-1.697), and previous influenza information (aOR = 2.241; 95% CI, 1.604-3.130) were positively correlated with vaccination willingness. In contrast, no previous QIV-related information (aOR = 0.490; 95% CI, 0.418-0.575), no perceived susceptibility of children to influenza (aOR = 0.576; 95% CI, 0.489-0.680), fear of side effects (aOR = 0.599; 95% CI, 0.488-0.735), concern that vaccines need to be carefully administered (aOR = 0.728; 95% CI, 0.593-0.894), and mistrust of new vaccines (aOR = 0.730; 95% CI, 0.628-0.849) were pivotal barriers hindering parents from having their children vaccinated. This study provides baseline information for future immunization programs and delivery, with the ultimate goal of increasing vaccine uptake and minimizing school-wide influenza outbreaks.
